Data Structures are typically used to organize, process, retrieve and store data on computers
for efficient use. Having the right understanding and using the right data structures
helps software engineers write the right code.
What are the types of Data Structures?
There are two types of Data structures -
Linear Data structure: If the elements of a data structure result in a sequence or a
linear list then it is called a Linear data structure. Every data element is connected
to its next and sometimes previous element in a sequential manner.
Example - Arrays, Linked Lists, Stacks, Queues, etc.
Non-linear Data structure:
If the elements of a Data structure result in a way that the traversal of nodes is
not done in a sequential manner, then it is a Non-linear data structure.
Its elements are not sequentially connected, and every element can attach
to another element in multiple ways. Example - Hierarchical data structure like trees.
Why are Data Structures important?
Data structures are a key component of Computer Science and help in understanding the
nature of a given problem at a deeper level. They're widely utilized in Artificial Intelligence,
operating systems, graphics, and other fields. If the programmer is unfamiliar with data
structure and Algorithm, they may be unable to write efficient data-handling code.
A strong grasp of this is of paramount significance if you want to learn how to organize
and assemble data and solve real-life problems
Almost all product-based companies look at how strong you are at data structures,
so it will also help you in your day-to-day work
Knowing when to apply the proper data structures is an important step to write
efficient code by managing data properly
